members as window screens which are relatively infrequently opened and closed for window cleaning purposes. It is .a feature of the invention to proii-lii vide a completely operative hinge consisting =of only two parts, and it is a further feature to provide two parts which are not only identical, but which are interchangeable. I It is a feature of the invention to provide 433% a hinge consisting of two flat thin plates, one adapted to be secured to a stationary part and the other to a swinging part, said plates having slotted portions coacting to form a M hinge connection. P The-invention has many other features and objects'whi'ch will be more fully described in connection with the accompanying drawing and which will be more particularly pointed out in and 'by the appended claims.

In the drawing; a Fig. 1 is an outside view of a window .provided with a screen adapted to swing about a vertical axisand illustrating the application thereto of the device of my invention. Fig. 2 is a fragmentary face view of the hin e on an enlarged scale and showing its disposition when'the screen is closed.

Fig. at is a sectional view on line 1 t look Fig. 8 is a view of one of the hinge plates as it would appear if attached to a fixed or. stationary part. I

Like characters of reference designate similar parts throughout the different figures of the drawing.

As shown, 1 indicates the siding of a house or building in which is fitted a window frame including stiles 2 and 3, the remaining portions of the frame being tin-important for the purposes of this disclosure. Disposed in the window frame is a window screen comprising the usual vertical members 4 and 5 and the usual horizontal members 6 and 7 between which is suitably mounted any form of screen cloth 8.

Reference will next be made to what more particularly constitutes the subject matter of this invention, namely, the hinge.

As shown more clearly in Figs. 7 and 8, the 3 improved hinge consists of two members 9 and 10, and said members are herein shown in the form of flat thin hinge plates of relatively thin guage material which of course will preferably be metal. It is a special feature of the invention to avoid the use of a pintle and to make the hinge of two parts. and it will be seen from these figures that the parts are identical in size and shape which consequently affords the valuable featu'reofv inter-changeability. Thus, in manufacturing the device, only one set of dies or forming mechanism need be made.

The plates 9 and 10, each have means such as holes 11 and 12, respectively, whereby they may be attached by screws or the like to their respective parts, and it will be noted that these holes are distributed near one side extremity of each plate thereby affording a pro ecting portion for each of said plates. The projecting portion of plate 9 is indicated at 13 and that of plate 10, at 14.

The plate 9 is shown in Fig. 7. in the position in which it would be disposed on a swinging member, such as the window screen, for instance, and said plate has a downwardly opening slot 15, terminating in a bight 16, the throat of the slot having diverging edges 17.

The plate 10 is shown in Fig. 8, in the position it would occupy of secured to a stationary part such for instance as stile 3, and the slot 18 extends through plate 10 and opens upwardly, as indicated at 19, and has a bight 20. While reference has been made to the ,fact that the plates are identical, which is a feature of great advantage, although not essential to the invention, still, the two plates have been shown in what would be their-operative positions and separate reference characters have been employed to more completely disclose the device. To further distinguish thesame, I will refer to part 21, of plate 9, as the anchorage portion thereof and to part 22 as the anchorage portionofiplate :10,'the projeeting portions 13 and 14 being suitably termed hinge portions. l

Rei'er-ing to Fig. 6', the anchorage portion 22 of plate 10, which is the supportingplate, would be secured by screws or the like to stile 3, in such a manner that the hingeor projecting portion 14 would extend outwardly, from 'the'stile, as shown, and in such'a position as to dispose the slot 18, as shown in Fig. 8. Anchorage portion 21, of plate 9, would be secured by screws or the like to the hlng'e member .ofthe-screen frame, in such a manner as to dispose portion 18 in prmecting relation and with the slot 15 thereof, which extends therethrough opening downwardly,

as shown in'Figj'l. z

With the parts in the position shown in Fig.6, the two plates Qanc'l are in crossed relation and slot spans the stock of portion 14 while slot 18 spans the stock ofpo rtion 13and the 'biglits 16 and 20 are in ened hinged and supported relation. Thus,

' m 'this position, the screen can either be attached to the frame or detached therefrom and when the screen hingedly connected,

I ing the outside thereof.

very slight space. In practice, I may proportion and arrange the parts so that the upright 4:, of the screen, will fit so snugly against the stile 2, as to force the screen toward thehinge side when closed and thereby insure theleast possible spread of the hinges andhence reduce the space between member :5 and stile 3, to a minimum; v In ractice, the slots 15 and 18 are made a tri e wider thanthe thickness of the hinge lates to facilitate movement of said plates into the abutting relation shown in Figs. 2

and 5. Further, the portions 23 and 24 are .a slight degree to'conform to sufliciently pliable to slightly flex to accomplish the overlapping relation necessary when the hinge plates are in abutting relation.

Because of the relatively light duty that this hinge is designed to perform, it is desirable to make the hinge of .a material that is pliable and capable of changing; its shape to t e stress that is imposedthereon. For instance, with a pliable hinge,'the same may be made flat, as

shown in Fig. 6, each hinge section initially occupying a single plane. After some use or actual service, the outer ends may separate, as shown in Figs. 2 and 5, or the hinge sections may develop offset portions or become offset with respect to the remainder of each section, .asZ-shown in Fig. 5,and even in this instance, the outer ends may separate or spread, as shown in said figure. Thencfore, it will be clear that, the changethat may occur, may result from the fact that the screen frame may be disposed either tooclose or too far from the window :frame. At any rate, the disclosure herein madeis suflicientto enable anyone skilled in the art tomake and use the device of this invention. i

It is believed that the device :of-my invention will be "fully understood from the herein shown one specific form of my invention, I do not wish to be limited "thereto except for such limitations as the claims may import.

I claim v I 1. In a hinge, a fiat supporting hinge adapted to be vertically anchored to a i! part and having a portion projecting outwardly and said outwardly pro ecting portion having a slot opening upwardly through said plate, and a flat swinging adapted to be vertically attached to a'swinging part and projecting outwardly therefmm and such projecting part having a slot opening downwardly throughsa'id plate adapted to span said supporting plate with the bights of said slots in 'bight hinged supported engagement for relative movement of said plates about a substantially vertical axis, said plates being in lateral abutting relation when the swinging part is closed and in substantially Greek Cross'relation when the swinging part is open substantially ninety degrees, andsaid plates being identical in size and shape and therefore interchangeable.

2. In a hinge, a pliable hinge plate adapted to be vertically anchored to a fixed part and having a vertical slot opening through the upper edge of said plate, and a pliable swinging hinge plate adapted to be vertically anchored to a swinging part and having a vertical slot opening through the lower edge of said plate, the pliable slotted portions meeting to form a hinge and the bi ht of the slot of the swinging hinge plate sibt being SUP 'foregoing' description, :and while I have M ported by the bight of the slot of said anchored hinge plate for relative movement of said plates about a vertical axis.

3. In a hinge for light weight members I such as window screens, a pliable hinge plate having an inner anchorage portion adapted to be vertically secured laterally against a fixed part and having an outer portion projecting from said fixed part and said outer portion having a vertical slot opening through the upper edge of said plate, and a pliable swinging hinge plate having an inner anchorage portion adapted to be anchored laterally against a swinging part and provided with an outer portion projecting from said swinging part and provided with a vertical slot opening through the lower edge of said plate, the projecting and pliable slotted portions to form a hinge and being relatively bent when said plates are in abuttingvrelation so that a portion of one plate extends on one side of the remaining plate.

In witness whereof, I have hereunto affixed my hand and seal.
